Abstract (in Japanese) (See Japanese page) 
(in English) Current service authorization systems have mostly assumed administrators are divided from ordinal users and the
all the responsibility and cost for managing services are concentrated on the administrators. Moreover, as the number of users
gets larger, the human relation between administrators and users get more scarce and users tend to behave more selfish and maliciously.
In this paper, we propose a new architecture named Social Networking Architecture (SNA) in which users authorize
each other when using services. In the SNA, a user who is authorized to use a service is able to be an inviter for the service.
An inviter is allowed to invite his or her trusted people based on his or her own responsibility and share the resources and
permissions that he or she has on the service with invitees. An invitee is also allowed to be an inviter and able to invite his or
her trusted people. Since each invitation is done with the human trust between two people, a network based on the human trust
chain is constructed for each service. Because of the properties, under the SNA, the management cost and risk for malicious
users due to the increase of number of users does not overwhelm administrators, and therefore, it is possible to construct a
scalable service network. Furthermore, since an invitation is performed based on the human relationship in the actual society,
invitees are discouraged to behave selfish and cause their inviters trouble. Because of this feature, it is expected that the SNA
automatically makes a secure service network.
